Perhitungan faktor utilitas baterai pesawat dengan menggunakan metode sistem dinamis untuk mengukur tingkat ketersediaan baterai

The role of the aircraft maintenance industry as an aircraft maintenance service which is expected to be able to maintain the survival of the aircraft itself. For example, PT GMF Aero Asia is one of the Strategic Business Units (SBU) owned by PT Garuda Indonesia which is specialized in aircraft maintenance, repair and overhaul services which include aircraft frames, engines, components and their support. In this study, a quantitative assessment of the availability and capability of maintenance facilities was carried out using a preventive maintenance method with a dynamic system model approach that describes the level of availability and maintenance capability of aircraft batteries. Calculations have been made with a computer program, POWERSIM, in actual conditions that in December 2020 the total number of batteries in maintenance was 102 batteries for Airbus types and 80 batteries for Airbus types. With the assumption that starting in 2021 there will be an increase in the number of aircraft by 1 (one) unit per month, then at the end of the study period until July 2021 the calculation of the utility factor will be as follows, the total utility factor for Boeing is still below 1, while for Airbus starting April 2021 the utility factor is above 1. So that the operator's ability to handle Airbus type battery maintenance is not sufficient. For this purpose, an alternative scenario needs to be created, namely scenario 1 by adding one operator per shift and scenario 2 by increasing the operator's workload in handling the number of batteries handled to as many as 6 battery units. The results of the calculation of the utility factor show that in both conditions the scenario gives a value below 1. The best choice in terms of simplicity in handling the number of operators, then the choice of condition scenario 2 is the best choice.

CV. Jasa Bhakti is a company producing agricultural equipment and automotive repair services. Employees who works in the production floor often ignore their own safety by not wearing shoes, glasses, masks, and other personal protective equipment so that they are vulnerable to accidents. The purpose of this study is to identify efforts of company to prevent work accidents. The method in this research is the hazard identification risk assessment and risk control (HIRARC). The data used in the form of historical data on the employees was obtained through observation, interviews, and documentation. The results obtained in this study are known to have 7 machine work processes, namely turning, welding, grinding, boring, carbide welding, scrap, and cutting. In this work, there are 27 hazards with hazard classes of 4 extremes, 4 high, 7 medium, and 12 low. The identification results indicate that the safety management system in the company is not good. Control measures that can be taken is in the form of making Standard Operating Procedures, procuring HSE division, engineering such as designing workplaces to prevent accidents, and education and advice to use personal protective equipment (PPE). This research can be applied to other industries.

The repair kit problem with imperfect advance demand information

To promote customer loyalty and generate revenue in after-sales service, many companies provide field repair services to their customers. Service technicians who perform these repair jobs typically carry a set of spare parts called a repair kit in their company van. The repair kit problem aims to determine which parts to include in this kit and in what quantity. Currently, many appliances are equipped with sensors that monitor their different functionalities. If an appliance breaks down because one of these functionalities is disturbed, then the respective sensor triggers a failure code that describes the appliance’s condition. From the service technician’s perspective, this failure code serves as potentially imperfect advance demand information for spare parts. In this paper, we present an extension of the repair kit problem that uses this information for the replenishment decision. We formulate this repair kit problem with advance demand information as a Markov decision process and propose two heuristic solution procedures. Our first heuristic is far-sighted and optimizes the inventory of all parts individually, while our second heuristic is a myopic greedy algorithm that considers all parts at once. We conduct an extensive numerical study to evaluate the performance of both heuristics and to identify which heuristic performs best under which circumstances. Comparing both heuristics to a state-of-the-art algorithm that disregards any available advance demand information, we find that utilizing this information yields substantial cost savings.

Comparative Study on the Hardness and Wear Resistance of the Remelted Gradient Layer on Ductile Iron Fabricated by Plasma Transferred Arc

Repairing the worn surfaces of wear-resistant workpieces, such as rollers, is one of the main application fields of surface treatment, but the repairing time is often not considered. In fact, the repairing time is very important, since it affects the repair quality and service life of wear-resistant workpieces. In this paper, a remelted gradient coating was prepared on a ductile iron plate by plasma transferred arc to simulate the repair treatment of wear-resistant workpieces. First, two positions in the remelted gradient coating were defined, i.e., the top of the gradient remelted layer was defined as M1, and the position where the hardness was two-thirds of the top of the remelting layer was defined as M2. Next, the time taken to repair the workpiece when the working surface reached M2 was proposed. Finally this method was verified by a comparative study on the microhardness and wear resistance of the M1 and M2. In this paper, the M2 was located at a ~0.5 mm from the top of the remelted gradient layer. The results show that the microhardness of the position of the M1 was higher than that of the position of the M2. However, the wear resistance of the M1 was worse, as confirmed by the wear rates. At the same time, cracks and fragments were observed on the worn surface of the M1 and M2 positions. Furthermore, the coefficient of friction (COF) of the position of M1 was noted to be first higher and subsequently lower than that of the position of M2, owing to the grinding ball entering the substrate. The abrasion mechanisms of both regions were observed to be complex, including oxidative wear, adhesive wear, delamination wear, and/or fretting wear. The experimental data indicate that it is feasible to determine the repair time according to the microhardness of workpieces.

Forest ecosystem service functions and their associations with landscape patterns in Renqiu City.

Forest ecosystems are crucial to the survival and development of human societies. Urbanization is expected to impact forest landscape patterns and consequently the supply of forest ecosystem services. However, the specific ways by which such impacts manifest are unclear. Therefore, to discuss the relationship between them is of great significance for realizing regional sustainable development. Here, we quantitatively assess the intensity of forest ecosystem service functions and forest landscape patterns in Renqiu City of China’s Hebei Province in 2019 using ArcGIS and FRAGSTATS. We characterize the relationships between forest ecosystem service capacity and landscape patterns, and identify strategies for the spatial optimization of forests. We find that the ecosystem service intensity of forests are significantly correlated with their spatial distribution, forest area ratio, and landscape patterns. Specifically, the percentage of landscape (PLAND) index, landscape shape index (LSI), and contagion (CONTAG) index indices display second-order polynomial relationships with various forest ecosystem service functions, with critical values of 80, 5, and 70, respectively. We propose that forest ecosystem functions can be optimized by optimizing forest landscape patterns. Specifically, to maximize the function of forest ecosystem services, managers should consider the integrity of forest ecosystems, optimize their ability to self-succession, repair service functions of key nodes within forests, enhance forests’ structural stability, optimize forest quality and community structure, and strengthen the efficiency of functional transformation per unit area. Finally, we propose a strategy for the spatial optimization of forests in Renqiu to optimize their associated ecosystem services. This involves protecting important areas for forest ecosystems, rationally organizing different ecological patches such as forests and water bodies to maximize their functions, strengthening the connectivity of scattered forests, and supplementing woodland areas.

Performance of Stochastic Inventory System with a Fresh Item, Returned Item, Refurbished Item, and Multi-Class Customers

This paper deals with an integrated and interconnected stochastic queuing-inventory system with a fresh item, a returned item, and a refurbished item. This system provides a multi-type service facility to an arriving multi-class customer through a dedicated channel. It sells fresh and refurbished items, buys used items from customers, refurbishes the used items for resale, and provides a repair service for defective items. The assumption of purchasing a used item from the customer and allowing them to buy a fresh item is a new idea in stochastic queuing-inventory modeling. To do so, this system has four parallel queues to receive four classes of customers and five dedicated servers to provide a multi-type service facility. Customers are classified according to the type of service they require. Each class of arrival follows an independent Poisson process. The service time of each dedicated server is assumed to be exponentially distributed and independent. This system assumes an instantaneous ordering policy for the replenishment of a fresh item. In the long run of this considered system, the joint probability distribution of the seven-dimensional stochastic process, significant system performance measures, and the optimum total cost are to be derived using the Neuts matrix geometric technique. The main objective of the system was to increase the occurrence of all kinds of customers by providing a multi-type service facility in one place. Buying a used item is unavoidable in an emerging society because it helps form a green society. Furthermore, the numerical result shows that the assumption of a system that allows a customer to sell their used item and purchase a new item will increase the number of customers approaching the system.

Search of arrivals of an m/g/1 retrial queueing system with delayed repair and optional re-service using modified bernoulli vacation

Single server queueing system in retrial is investigated, as well as optional re-service,customer search and delayed repair. Furthermore, the server is permitted to take a vacation under Modified Bernoulli vacation. In this model, some of the customer’s seek voluntary reservice for the identical service taken, dissatisfied with the first attempt without entering the retrial group (probability r1) or leaving the service area (probability 1 – r1). The failing server's repair begins after an arbitrary length of time termed delay time has passed. The supplementary variable technique is used to calculate orbit size, server status, and performance metrics. We explore several special situations of our suggested model and compare the results to previous research.

After-Sales Service Contracting: Condition Monitoring and Data Ownership

Problem definition: Condition monitoring (CM) of durable assets, whereby sensors continuously monitor the health of an asset, is heralded as a key application of the Internet of Things. However, questions about ownership of the sensor data are seen as a key barrier to adoption. We model an after-sales supply chain in which the asset manufacturer provides maintenance and repair services to a customer that operates the asset. The asset condition deteriorates in a stochastic fashion and will eventually fail if not repaired. Methodology/results: We analyze a performance-based contracting problem considering manufacturer maintenance effort (the condition at which preventive maintenance is performed) and customer operating effort (which reduces the rate of condition deterioration). With information asymmetry on the customer’s effort cost, we analyze this contracting problem in a principal-agent model with double moral hazard. In the centralized setting, we establish that the benefit of CM increases and then decreases in the asset’s deterioration rate and that CM may increase or decrease the benefit of customer effort depending on the deterioration rate. In the decentralized setting, we prove that CM always benefits the manufacturer and the supply chain, but it may hurt the customer if the asset reliability is sufficiently high. Managerial implications: These results have important implications for the effect of sensor-data ownership. The manufacturer will adopt CM if it owns the data, but the customer may block CM adoption if it owns the data. We show that this CM adoption barrier can be overcome by the manufacturer offering to pay an appropriate data access fee. However, under this arrangement, the manufacturer may not benefit from a more-effective customer operating effort. We discuss the resulting implication on the manufacturer’s product design and the business model between selling and leasing.

Negotiation for service contracting: incentives, bargaining power, and customer risk aversion

AbstractIn this paper, we analyze negotiation of service contracts when an equipment user (customer) outsources product failure repair service to an MRO (Maintenance, Repair, and Overhaul) supplier. The customer is risk averse due to serious consequences of system disruption. The two parties negotiate pricing terms and repair rate. We model the bilateral negotiations under three types of service contract: (i) fixed‐fee contract under which the customer pays a lump sum, (ii) pay‐per‐repair contract under which the customer pays for each repair incident, and (iii) uptime‐based contract under which the customer pays for product uptime. We investigate how different incentives under each contract interact with agents' bargaining power and customer risk aversion in the negotiation process, both theoretically and numerically. Despite that previous studies have shown that fixed‐fee contract generally does not provide incentives for suppliers to invest in repair capacity while uptime‐based contract does, we find that under a bargaining framework fixed‐fee contract can result in the highest (yet suboptimal) repair rate. Furthermore, consensus on contract types may not be achieved between the two parties. For the supplier, uptime‐based contract can result in the highest payoff while pay‐per‐repair contract leads to the lowest. For the customer, it may prefer to choose pay‐per‐repair contract when it is less risk averse and when the supplier has more bargaining power. Our results show some unexplored merits of other types of contracts when the advantages of uptime‐based contract have been highly cited.

A descriptive analysis of wheelchair repair registry data

ABSTRACT Wheeled mobility and seating (WMS) devices allow users to achieve greater mobility independence. Previous studies determined that 53% of wheelchair users required one or more repairs over a 6-month period; however, there are a limited number of studies that have evaluated types of repairs. The purpose of this study was to describe the types of manual wheelchair, power wheelchair, and scooter repairs within the Wheelchair Repair Registry (WRR) and examine the association between WMS devices and the frequency of repairs. A dataset of 4,645 devices distributed in the United States was collected from equipment suppliers who performed and logged community-based wheelchair repair services. The results demonstrated common repairs found across devices were within the wheels/tires/forks and batteries/cables categories. Device type was the most significant predictor of variance in the number of repairs. Customizable manual wheelchairs, tilt-in-space, Groups 2 & 3 power wheelchairs, and scooters were associated with higher number of repairs compared to non-customizable manual wheelchairs, pediatric, heavy-duty manual wheelchairs, and Group 4 power wheelchairs. The higher failure rate found in specific devices may be associated with a population of more active users, environment/conditions where equipment is used, time spent in equipment, additional features on device, or lower durability.

Extending the Life Cycle of EEE—Findings from a Repair Study in Germany: Repair Challenges and Recommendations for Action

The increasing amount of waste from electrical and electronic equipment and the resulting environmental issues are challenging, since product life cycles are too short, and companies continue to rely on linear (business) models. The Circular Economy is an approach to meet these challenges by extending the product lifetime. One way to extend the product lifetime is to repair them. However, since there has been no detailed research on the repair sector yet, this article aims at conducting a repair study in Germany to understand the repair process and get insights into typical failure patterns. Therefore, we analyze the repair sector’s current barriers from different perspectives, especially of customers and businesses. We discuss the results of the repair study, where 382 repair attempts were conducted, with a total success rate of 55%. Moreover, the participants were interviewed to understand their barriers and motivation for repair. Based on the study’s interim findings, recommendations for action are given to make the repair services more attractive for the repairer and customer. Based on the findings, an interdisciplinary approach to improve repair processes by using a digital repair portal is derived.

Drivers of the consumers’ intention to use repair services, repair networks and to self-repair

Repair is a central component of a circular economy to extend the operational phase of products. Yet, the number of repair service providers as well as demand for repair have declined over the last decades, while more products than ever before were sold. Thus, for a successful transition from a linear to a circular economy the demand for repair services must be boosted to promote repair business. A starting point to achieve this goal is to increase knowledge about the end consumers’ intention whether to repair broken products or not. An extensive literature research revealed a comprehensive set of drivers of the repair intention covering aspects related to environmental protection, social acceptance, and economic considerations as well as socio-demographic variables, past behaviour, and perceived repair difficulty. Those factors are not only relevant for a specific product category but for repairs of consumer goods in general. The aim is to evaluate the relevance of those drivers for three different repair intentions: (1) to make use of repair service providers, (2) to self-repair broken items, and (3) to use repair service providers incorporated in a repair network. A quantitative online survey was designed, and distributed in Styria, Austria. By means of a structural equation model the acquired data of 900 respondents was analysed. The results emphasise the trade-off between acting environmentally-friendly and economic aspects like repair cost and time, but also highlight the effect of government intervention – in the form of setting up a network and financial support for repair – on shaping this trade-off. Furthermore, past behaviour is found to strongly drive repair intention. Our research contributes to scientific literature by shedding light on the influence of diverse drivers on different repair intentions. It is also relevant for supporting repair companies’ decision making with respect to repair service design, as well as public authorities interested in promoting repair.

Android-based household electronic maintenance reminder system

Along with the development of electronic devices used in households such as fans, rice cookers, and others do not always function appropriately. There are times when the device is damaged, and the user will try to fix it. One way to fix this is to find an electronic equipment repair place. Therefore, the electronic user will lose time and energy to find a service place. So we need an online ordering service that specifically handles the maintenance and repair of household electronic equipment. With this system, it is also beneficial for business actors of electronic equipment repair and maintenance services. They will effortlessly get information about customers who need repair or maintenance services for electronic equipment. Thus this system is expected to facilitate service users and increase the income of service users.

Design Thinking with Appropriate Technology for Improving Social Sustainability: Critical and Comprehensive Criteria

Current appropriate technology promoting social sustainability for rural, underprivileged populations is often plagued by lack of affordability, maintenance, and personal training, and is also empathetically disconnected from local people and culture. This study proposes criteria for balancing design thinking processes and appropriate technology for social sustainability. In this study, we concretized five assumptions for design thinking processes: user-oriented design with mass productivity; reiterative nature through user satisfaction surveys; affordability for purchase, maintenance, and repair services; local appropriateness; and eco-friendliness with environmental sustainability. Next, we applied the criteria to 28 representative cases from the water, energy, health, shelter, and transportation fields. The cases were evaluated using qualitative content analysis. Findings show that the criteria are necessary for setting economic, social, and environmental development goals for underprivileged regions after considering local contexts. Cultural empathy and collaboration with locals are key for finding practical solutions and co-creating options iteratively. Further, the cases were compared quantitatively using radar diagrams, histograms, and graphs showing average values and standard deviations, providing an objective measure for appropriate technology. Notably, both qualitative and quantitative approaches can serve as useful guidelines for designers, developers, and local users when developing appropriate technology for social sustainability in underprivileged regions.
